On the Day of Divorce, My Ex-Wife Knelt in the Rain and Begged Me to Come Back.

Male Protagonist: Zhou Jin - On the surface, he is the "useless" son-in-law of the Jiang family, but in fact he was once the "King", the world's top financial trader. He became anonymous because he was tired of fighting and because of his love for Jiang Xuening. Possess extraordinary powers of observation (control of details) and almost instinctive crisis-handling abilities (derived from past experiences). Weaknesses: Excessive dedication to the identified "family" and emphasis on affection. Ex-wife: Jiang Xuening-Bingshan President of the Jiang Group, stunningly beautiful, with outstanding abilities but arrogant and cold personality. She relies heavily on Zhou Jin's care in life without realizing it, and takes his contribution for granted. There is an obsession filter in my heart for "White Moonlight" Lu Jingchuan (who saved her when she was young). Shen Zhixia - an internationally renowned jewelry designer and Zhou Jin's best friend in the orphanage when they were young (they once redeemed each other). He has a warm and tough personality, is extremely talented, and has insight into people's hearts. After returning to China in search of design inspiration, he is the only person who knows part of Zhou Jin's past. Bai Yueguang/Villain: Lu Jingchuan - an upstart business man who appears to be as gentle as jade, but is actually a careerist who will do whatever it takes to achieve his goals. The "rescue" incident back then was a well-planned plot to get close to the Jiang family. Seeing Zhou Jin as a thorn in his side, he wants to annex the Jiang family.
